Abilities of Imaging Modalities in Diagnostics of Cystic Lymphangiomas at a Stage of a Surgical Treatment

Since 1994 till 2006 years in Vishnevsky institute of surgery there had been treated 18 patients at whom a cystic lymphangioma was suspected. Patients's age ranged from 15 to 75 years. There were a solitary lesion in 17 patients and one had the abdominal lymphangiomatosis. A complex examination and a surgical treatment were performed to all of patients. A combination of diagnostic modalities including complex ultrasonography, CT and MRI with contrast enhancement allowed to diagnose and to localize a cystic lymphangioma, to define its relationship to surrounding tissues and main arteries, and to chose a minimally invasive tactic of a surgical treatment. Despite the fact, that performing CT we depicted thin septa only in 50%, at MRI and US we visualized them in 100% of cases. MRI can more clearly delineate the tumor relative to surrounding organs and tissues and complex ultrasonography can define vessels' state going beside. In some cases MRI allowed to reveal “a neck” of a cystic lymphangioma. Based on all aforesaid we believe, that examination of the patients suspicious to have a cystic lymphangioma should be confined to a complex ultrasonography and MRI, as soon as a combination of these two methods gives all the information needed for surgical treatment without any radiation exposure. 3D ultrasonography in some cases allows to precise tumor's relations to nearby vessels.
